In this paper, a monitoring system of cold storage ring is designed based on the characteristics of Zigbee wireless sensor network (WSN) and the actual situation of cold storage, which Including ZigBee network hardware and software design. The ZigBee WSN routing protocol Cluster Tree is improved, neighbor table information is drew into in the Cluster Tree algorithm, also studied the selection of nodes in neighbor table, It is beneficial to find an optimal path and reduce the delay of data transmission. The Zigbee WSN is used in the cold storage monitoring system, so it can be used for a long time with only one installation, which can solve the problems of complicated equipment and low efficiency in the traditional cold storage management. The test results show that the system meets the design requirements, so as to achieve the purpose of real-time monitoring of cold storage items.
